About the RoleAs the Founding Software Engineer on our Data Platform team at Arlo, you will build the foundation for our ML-driven health insurance quoting system. You'll design and implement the entire data infrastructure that powers our core product, working at the intersection of data engineering and machine learning operations.
Key Responsibilities:

• Design and build scalable data pipelines that process billions of healthcare claims records
• Develop robust ETL workflows to ingest, normalize, and transform medical data from multiple sources
• Create infrastructure for real-time ML inference serving hundreds of millions of predictions
• Build developer tooling to accelerate the work of our data scientists and ML engineers
• Architect and implement monitoring systems to ensure data quality and model performance
• Optimize PySpark code for feature construction to improve performance and efficiency

Projects You'll Lead:Healthcare Data Platform:

• Build a unified data platform that ingests medical data from diverse sources and normalizes it for both training and inference
• Develop workflow orchestration tools to automate complex data processing pipelines
• Create CI/CD pipelines for reliable deployment of data transformations and ML models
• Refactor and optimize existing PySpark code to enhance performance and scalability

ML Production Infrastructure:

• Design and implement real-time inference systems that can handle high-volume prediction requests
• Build infrastructure for A/B testing and controlled model rollouts
• Develop monitoring tools to track model performance and data drift in production

This role combines data engineering and ML infrastructure expertise to create the backbone of our AI-powered health insurance platform. You'll work across the full ML lifecycle, from initial data processing to production deployment and monitoring.
